I'd say just be patient. Those lower leaves will all be pruned off as soon as the plant takes off and starts really growing. Those lights are definitely too far away though. I'm running a 1000W MH on my plants and the light is less than a foot away and they are thriving. Since the lights you're using are so weak I would definitely keep them at least 6" away from the plants if not closer.
I'd consider getting some Thrive Alive B-1 Red (not to be confused for Super Thrive) for foliar feeding and spray them as many times a day as you are around to do so. Mix up a liter of water and 5ml of Thrive Alive in a spray bottle and mist your plants once a day to all day long if you'd like. It's only about $16 for a 250ml bottle which will make 50 liters of foliar spray. With your plants being so small I don't see you using more than 1 or 2 liters a week for now. It'll strengthen your foliage, reduce stress, green up your leaves, and help with rooting. It's also great to add to the reservoir at 12ml per gallon.
